100

When an organism has 2 different alleles of a trait.

Heterozygous

100

The generation with which we start to study genetic combinations

P generation 

100

A gene that only expresses in the absence of a dominant.

Recessive

100


When neither allele for a trait is completely 

dominant, resulting in a heterozygous phenotype 

that is an intermediate blend of the two 

homozygous parental traits.


Incomplete dominance

100

One snapdragon in the P generation is red, and the other is white. What will the F1 generation outcome colour be? Snap dragons follow incomplete dominance.

Pink

200

What is the process called when a female gamete fuses with the male gamete to produce a seed?

Fertilization

200

  • A gene variant that expresses its trait in an organism's appearance (phenotype) even if only one copy is present, masking the effect of another allele.

Dominant gene

200
What was the organism Mendel studied?
What is Pea Plant?
200

Organisms that carry pollens to the female flower.

Pollinators/Carriers

200
What are Punnett squares?
What is the possible offspring that could be formed from the gametes of the parents?
300

Who is known as the father of Genetics?

Gregor Mendel

300

Observable and measurable characteristics of an organism

Phenotype

300

If purple is dominant to white, what color flower is Pp?

Purple

300

A goat that has both red and white hair but its presented in patches. What is that Codominance, Incomplete Dominance ?

Codominance

300

How many types of blood groups are there?

8

400

A different version or variation of the same gene.

Alleles

400

A number that describes how likely it is that an event will occur.

Probability

400

If you crossed BB with bb, all of the offspring would have this genotype.

Bb

400
Distinguish between the terms phenotype and genotype?
What is the combination of the alleles and the physical traits of an organism?
400

If a family has 3 boys, what is the probability that the parents will have a girl next time?

50 %

500
Genotype describes the genes of an organism and __________________ describes the way an organism looks.
What is phenotype?
500


When the alleles are neither dominant nor recessive, 

both alleles are expressed in the offspring.


Codominance

500
What was Mendel's ratio for F2 generation?
What is 3:1?
500

How many pairs of chromosomes are there in humans?

23
